Grub broke Windows bootloader?

[suburbandisposal]

So I'm basically trying to convince grub to get my foot in the door then, got it. Also the "I have access to the GRUB menu but my OS does not start" option is the accurate one , is it safe to assume this is the correct option? Or is reinstalling GRUB all together better

and as for "place grub into", is there anywhere in particular I should choose for that/avoid/leave it alone?

thanks again for the info, I'm accident prone so I prefer to be over prepared if I can help it
